Definitions

  • the invention relates to a bending machine for sheets with a support device for receiving the sheet to be bent.
  • a bending machine for sheets which has a support table with parallel to the bending edge adjustable support elements.
  • the present invention has for its object to provide a bending machine which can handle as variable as possible already preformed or bent sheets, or which can produce a variety of bends on a sheet.
  • An advantage of the embodiment of the invention is that by the running at right angles to the hold-down edge first gap or parallel to the hold-down edge extending second gap, which are formed on the support device and which are variably adjustable, and sheets can be placed on the support device which already have existing bends and thus are not flat in the region of the support device. As a result, the bending machine is more flexible, so that a total of a larger number of differently shaped sheets can be produced.
  • At least one of the two support elements in each case comprises contiguous and guided on the support module segments.
  • segmented support elements can be moved as needed in their position or that they can be partially removed from the area of the support plane and can be arranged to save space within the support module.
  • At least one actuator preferably electromotive drive, is arranged per support module, by means of which at least one of the support elements arranged on a support module is adjustable.
  • the advantage here is that at least one of the support elements is adjustable and thus the size of the second gap is variably adjustable.
  • two actuators preferably electromotive drives, are arranged per support module, by means of which the first and the second support element are independently adjustable.
  • the advantage here is that thereby not only the size of the second gap is variably adjustable but that the position of the second gap can be varied.
  • the individual support modules can thus Fully automatically adapted to the requirements for processing of different sheets.
  • the support elements in particular the individual segments, can be rolled up on a storage roll. It can thus be achieved that the support elements, when they are moved from the support area and thus the second gap is increased, can be moved to save space in the support device. By rolling up the individual segments on a storage role they can be arranged as possible space saving on the storage role similar to a roller door.
  • the storage roller is coupled by means of a belt drive with a drive unit.
  • the advantage here is that the drive unit can be spaced from the storage role by the belt drive and thus the drive unit can be arranged in a region of the support device in which it does not adversely affect the functionality of the support device, so that by the drive unit for the support the sheet required space is not limited.
  • the storage rollers of at least two of the support modules are rotationally coupled, wherein the rotational movement is transmitted by means of a longitudinally extending drive shaft with polygonal cross section and wherein the drive shaft is driven by a rotary drive and wherein the storage rollers in the longitudinal direction of the drive shaft displaceable are.
  • a drive shaft can be arranged with a polygonal cross section, which is driven by a drive unit.
  • the individual support modules can in this case be arranged displaceably in the longitudinal direction on the bending machine, wherein the storage rollers have a polygonal inner cross section, which corresponds to the polygonal cross section of the drive shaft.
  • the support modules are displaceable by means of a manipulator in the longitudinal direction of the bending machine, wherein the manipulator is a coupling element having on-demand coupling with the support modules.
  • the manipulator comprises a manipulator arm, which is designed such that the manipulator can reach different support modules.
  • a manipulator which is used for handling sheet metal workpieces, can also be used to position the individual modules.
  • the manipulator comprises a traction means with a driver element.
  • a trained manipulator can be constructed as simple as possible and can extend over the entire width of the bending machine, so that all support modules of the support device can be moved by means of the manipulator.
  • each of the support modules has its own actuator and is displaced by this in the longitudinal direction of the bending machine.
  • the advantage here is that the support modules can be moved at the same time and independently and thus the support device can be prepared within a very short time for the circulation of variously designed sheets. Thus, the setup time can be shortened and thereby the utilization of the bending machine can be increased.
  • a parking brake is formed per support module, by means of which the support module can be fixed in its position.
  • the advantage here is that thereby the individual support modules can be fixed in position and thus an undesirable move the support modules can be prevented.
  • the individual segments of the support elements are coupled together by an elastic coupling element. It can thereby be achieved that the individual segments of the support elements are flexibly connected to each other.
  • the individual segments of the support elements each have a roller guide through which they are guided in a support module.
  • the advantage here is that the individual segments of the support elements can thus be performed smoothly in a support module, such a roller guide is subject to only minor wear.
